You may think that all roofs are created equal, but this isn’t exactly the case. While hopefully, each roof in your neighborhood is high in quality, many will vary in terms of the overall layout.
For example, today we’ll be focusing on why some homes need intake ventilation as well as exhaust ventilation — as was the case in the home featured in the video.
Today, we’ll discuss why some homes require this extra source of ventilation and what issues could arise if the proper intake ventilation isn’t installed. First, let’s break down the difference between exhaust and intake vents.
Exhaust Vents vs. Intake Vents
Exhaust vents are used to ensure air flow from the attic to the outside of the home. When they are properly installed, the air in the attic and ventilation spaces will exit the home and move to the exterior of the house.
Exhaust vents are crucial to ensuring that your home has clean air, as it pulls odors, fumes, and moisture from the air and pushes it outside.
Air intake vents are used to allow outside air to enter into attics and ventilation spaces. Intake vents should be located along a roof assembly’s lowest eave at or near soffits or eaves.
Intake vents are best used with exhaust vents that are located at or near a roof assembly’s peak. This configuration of ventilation air intake along low points and exhaust at high points takes advantage of natural convection.
What Happens if You Don’t Have the Proper Ventilation?
With the home, we are talking about today in this post, we investigated the attic and saw that the layout inside meant that an exhaust vent system wasn’t going to be enough.
In order to ensure the safety of the home, an intake vent was going to be needed.
Without an intake vent, this home would have run the risk of ice dams in the winter. This is because the temperature of the roof would have been warmer near the top of the roof and colder near the bottom. This is a prime reason for ice dams forming.
In addition, without an intake vent, the shingles will become way too hot and will, therefore, go through more wear and tear and will not last as long.
So, as you can see, there is a whole system within a roof that works together to ensure that the roof is stable.
